import std; void main() { struct S { immutable int value; } assert(chain([S(5)], [S(6)]).joiner.same([S(5), S(6)])); }

Ran into it again just now. Bleh. This is also one of the issues that need https://github.com/dlang/phobos/pull/8674

The example was rubbish. How about this: ``` void main() { import std.algorithm : joiner, map; import std.array : array; static immutable struct S { int[] arr; } auto range = [S([3]), S([4, 5])]; assert(range.map!"a.arr".joiner.array == [3, 4, 5]); } ```
